Ramon Posted January 15, 2017 Share Posted January 15, 2017 I bought some coprolites ( Mineralized dung) that came from Madagascar. I have some questions. What is the real age of them? Some sellers on the Internet say it's from the Eocene, others say it's from the pliocene. What animal did they come from? They were labeled as turtle coprolites. And last, Are they really coprolites? They could easily be concretions or some other geological thing. I have not been able to find much information.

-Andy- Posted January 17, 2017 Share Posted January 17, 2017 I have mine labelled as Turtle Coprolite 72.1 - 61.2 mya (late Cretaceous to Paleocene) Mahajanga, Madagascar Admittedly though, their ID is problematic. I am seeking more info on these as well. Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!

Ramon Posted January 17, 2017 Author Share Posted January 17, 2017 Yeah, looking forward to get more information about this.

FossilDudeCO Posted January 18, 2017 Share Posted January 18, 2017 Hey ramon. Several geologists have told me these are limonite concretions. Still others agree they are "turds" I no longer sell them since Noone can agree! That is a decent sized one you have there! Link to comment Share on other sites More sharing options...

And the biggest one is 9 cm!!!

-Andy- Posted January 30, 2017 Share Posted January 30, 2017 These are claimed to be coprolites encased in Siderite, and come from Besiboko of Mahjanga, Madagascar according to two dealer sites I checked. Can anyone verify this? Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!
